Has the infection burden associated with CIED implantation in the United States changed between 1993 and 2008?
The incidence of CIED infections in the US increased significantly after 2004, correlating with a higher burden of patient comorbidities, and is associated with increased mortality and healthcare costs.
OBJECTIVES: We analyzed the infection burden associated with the implantation of cardiac implantable electrophysiological devices (CIEDs) in the United States for the years 1993 to 2008. BACKGROUND: Recent data suggest that the rate of infection following CIED implantation may be increasing. METHODS: The Nationwide Inpatient Sample (NIS) discharge records were queried between 1993 and 2008 using the 9th Revision of the International Classification of Diseases (ICD-9-CM). CIED infection was defined as either: 1) ICD-9 code for device-related infection (996.61) and any CIED procedure or removal code; or 2) CIED procedure code along with systemic infection. Patient health profile was evaluated by coding for renal failure, heart failure, respiratory failure, and diabetes mellitus. The infection burden and patient health profile were calculated for each year, and linear regression was used to test for changes over time. RESULTS: During the study period (1993 to 2008), the incidence of CIED infection was 1.61%. The annual rate of infections remained constant until 2004, when a marked increase was observed, which coincided with an increase in the incidence of major comorbidities. This was associated with a marked increase in mortality and in-hospital financial charges. CONCLUSIONS: The infection burden associated with CIED implantation is increasing over time and is associated with prolonged hospital stays and high financial costs.
“The number of Americans receiving pacemakers and defibrillators has dramatically increased. This analysis shows that the infection risk associated with these devices has, unfortunately, increased as well.”
Greenspon et al. (Mon,) conducted a observational in Cardiac implantable electrophysiological device (CIED) implantation. Cardiac implantable electrophysiological device (CIED) implantation was evaluated on Incidence of CIED infection. The overall incidence of CIED infection in the United States between 1993 and 2008 was 1.61%, with a marked increase starting in 2004 that coincided with rising major comorbidities.
